OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 433,639, dated August5, 1890.

Application led April '7, 1890. Serial No. 346,808. (No model.)

To all whom, it may concern:

Be it known that I, ERNEST M. ARNOLD, of Thompson, in the county ofI/Vindham and State of Connecticut, have invented a certain new anduseful Improvement in Oil-Burners, of which the following is aspeciiication.

My invention relates to an improvement in burners for feeding oil to aliame in a finelydivided state.

A practical embodiment of my invention is represented in theaccompanying drawings, in whichi Fig. l is a View of a burner in centralsection, the feed-pipes being shown partially in section. Fig. 2 is arear view of the burner, the outer shell being removed; and Fig. 3 is aView of the burner in side elevation, partly in section.

A leading feature of my invention, in connection with various details ofconstruction, is a rotary part actuated by the pressure of the iiuid,and which engages a combustible liquid fed thereto in such a manner asto iiow off in a nely-subdivided state.

A represents an oil-feed pipe, the same being surrounded by a pipe B,leaving an annular space around the pipe A, along which a tluid-stean1or air, for example-may be forced. An inlet-opening to the pipe B isdenoted at C. On the end of the feed-pipe A the inner iiXed portion D ofthe burner is secured conveniently by means of a screwthreadedconnection, as represented at d.`

The burner-section D consists of a portion d', having a taperedperiphery d2, flaring outwardly toward the discharge-face of the burnerand provided on said periphery with a series of channels d3, extendingobliquely to a plane passed through the longitudinal axis of theburner-section. Centrally from the face of the disk portionl d of theburnersection D a cylindrical portion dl projects. A cylindrical chamberI is formed at the end of the feed-pipe A within the burner-section D,and feed-openings 'L' radiate from the curved wall of said chamberthrough the projecting portion d4.

A rotary burner-section F is provided with a centrally-located hub f, bymeans of which it is loosely mounted on the projection d* of theburner-section D. The rotary section F is provided with anoutwardlylaring rim f',

in the periphery of which a series of channels f2-is formed, the saidchannels f2 extending obliquely across the periphery in a directionopposed to that in which the channels d3 of the burner-section D extend.

The section F is of such diameter and so formed that when placed injuxtaposition to the portion CZ of the burner-section D its peripherywill form a continuation of the periphery of the said portion d. The rimof the section E is connected with the hub portion f, preferably by aweb f3, as shown. The channels f2 in the periphery of the section Fconnect with channels f4, which extend obliquely along' the inner faceof the rotary section E, between it and the portion ci of the section D,into communication with the radial openings t'. The rotary section E isconveniently secured in its position bya cap G, xed to the outer end ofthe cylindrical portion d4 by means of a cap-screw H.

A funnel-shaped shell E is provided with a `screw-threaded stem e, bymeans of which it is screwed onto the end of the duid-feed tube B, andwhen in position the inner wall of its flaring portion contacts with theperiphery of the burner-section D and lies in close proximityto theperiphery of the rotary section F.

The operation is as follows: The liquid fuel, being forced under asuitable pressure along the feed-pipe A into the cylindrical chamber I,is distributed through the openings i' into contact with the rotarysection F. At the same time the luid-steam or air, for example-undersuitable pressure is forced along the pipe B and through the ehanneld8in the stationary section D and impinges against the opposing walls ofthe channels f2 in the rotary section F, causing said section to rotate.As the section F rotates it causes the liquid fuel to tiow along thechannels f4, and thence along the channels f2, under the influence ofthe centrifugal force, from whence it is thrown oit into the flame in anatomized or iinely-divided state, and thoronghly commingles with thesteam or air issuing from the same channels.

liquity of the channels d in the periphery of the section D directs thejets of steam or air in more direct opposition to the channels f2 in therotary section, and at the points where The Obthe steam issuing fromsaid channels d3 irnpinges upon the Walls of the channels f2 the liquidfuel will be thoroughly agitated and subdivided, and in ahighly-favorable condition to become more completely atomied orsubdivided as it is thrown from the ends of the channels f2 into theiiame.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention; hence I do not Wish to limit myselfstrictly to the construction herein set forth; but

\Vhat I claim as my invention is- 1. An oil-burner provided with anoil-feed pipe havinglaterally-extending oil-discharge openings leadingtherefrom, a pipe for supplying a fluid under' pressure,outwardly-inclined fluid-passages leading from the fluidsupply pipeacross the paths of the jets from the said oil-discharge openings, and arotary section in proximity to the paths of the oil and fluid jets fromthe said openings or passages, substantially as set forth. g

2. An oil-burner comprising a stationary section provided with anoil-receiving and Oil-distributing chamber, a rotary section mounted inproximity to the stationary section, the said sections being providedwith channels across their peripheries, and an inclosing shellsurrounding the peripheries of the sections, substantially as set forth.

3. An oil-burner comprising a stationary section and a rotary sectionloosely mounted on the stationary section, the stationary section andthe rotary section being provided With tapered peripheries, and havingchannels across said peripheries, the stationary section provided withan oil-receiving cham ber, having` oil-outlet openings leading to therotary section, and a shell surrounding the peripheries of the sections,substantially as set forth. I

4. The combination, with the stationary section provided with an oilreceiving and distributing chamber, and having a tapered periphery Withchannels across it, of a rotary burner-section mounted on a projectedportion of the stationary section and provided With a tapered peripheryhaving channels arranged obliquely across the same, and a shellsurrounding the tapered peripheries of the sections, substantially asset forth.

5. The combination, with a stationary section provided with an oilreceiving and distributing chamber, and having a tapered periphery, withchannels extending obliquely across the same, of a rotary sectionloosely mounted in proximity to the stationary section and provided Witha tapered periphery having channels arranged obliquely across the samein a direction opposed to that in which the channels of the stationarysection extend, and an inclosing shell, substantially as set forth.

6. The combination, with the stationary section provided With anoil-receiving chamber and openings radiating from said chamber throughthe Wall of the section, the said section being provided With acylindrical projection and with a channeled periphery, of a rotarysection loosely mount-ed on the said cylindrical projection, and havingchannels on its periphery in communication With the radial openings ofthe stationary section, and a surrounding shell provided with an openingfor the entrance of the fluid into said channels, substantially as setforth.
